The 26-year old was a target for Bolton boss Dougie Freedman during the summer, with the club keen to offer the midfielder a short-term deal.
However, nothing came of the talks, and the former Republic of Ireland Under-21 international started the season in London - in the Eagles reserve squad.
Whilst interest in Garvan cooled over the past weeks, the former Ipswich man was not included in Palace’s 25-man squad for Premier League action, and having been frozen out of the playing squad he is said to be keen to move away from Selhurst Park.
The Palace management are keen to see Garvan leave the club, with him unavailable for Premier League action, and, as reported by The Bolton News, Wanderers are likely to once again show interest in their former target, with the loan window opening today.
A number of clubs could show interest in the midfielder, who spent the second half of last season with Millwall on a temporary deal. Since making his debut for Ipswich Town in 2005, Garvan has gone on to make 238 appearances in the Championship, playing a key part in Palace winning promotion to the top flight in 2013. However, his Premier League career has failed to pan out, and the 26-year old made just two appearances for the Eagles last season - both coming under the management of former coach Ian Holloway.
It was Holloway who then brought Garvan to Millwall in February 2014, and he is likely to show interest in the payer again, having played a key part in helping the Lions secure their Championship status.
